The Friends of Lake Sonoma welcomes you!

The Friends of Lake Sonoma is a cadre of volunteers that supports the interpretive and educational programs managed by the U.S. Army Corps of Engineers at Lake Sonoma.  Due to federal budget shortfalls, we also provide funding to help maintain the park and keep key facilities -- including the Milt Brandt Visitors Center -- open to public access.  We welcome your help -- financially through monetary and in-kind donations or through your service as a park volunteer! 

Yorty Creek is now open!

Beat the heat on Labor Day.  Join us at the lake!  Temoeratures in excess of 100 degrees are predicted and it's always cooler on the water.  Rent a kayak at Yorty Creek or the Lake Sonoma Marina!

Lake Sonoma Steelhead Festival draws record crowds

It's a record! Upwards of 8,000 people joined us for the Annual Lake Sonoma Steelhead Festival this year on Feb. 11th.  Perfect weather in the midst of a stormy season helped boost attendance.  Especially popular this year were the new bubbles show, kids fishing, the Sonoma County Bird Rescue, food trucks, wine and beer, plus the music of HotGrubb!  Save the date for 2018:  February 10th!  Special Note:  The Sonoma County Board of Supervisors awarded a Concurrent Gold Resolution thanking the Friends of Lake Sonoma and sponsors of the 9th Annual Lake Sonoma Steelhead Festival on March 28, 2017.


Milt Brandt Visitors Center

The Milt Brandt Visitors Center at Lake Sonoma is now open daily!  Hours are 9 a.m. to 4 p.m.  Friends of Lake Sonoma is looking for volunteers to help staff the center and give fish hatchery tours during the Steelhead Run, which is January through April.  If you can help, contact us at 

We tip our cap to this year's Steelhead Festival sponsors!
